Stringent limit on space-time variation of fine-structure constant using high-resolution of quasar spectra
We have obtained a new limit on the space-time variation of the fine-structure constant [Formula: see text] using the observations of Mg II line in quasar J110325-264515 spectra with redshift [Formula: see text]. The obtained parameter is [Formula: see text]. It was derived from the comparison betwe...
